In large bowl combine the dry ingredients. Add dissolved yeast
and chicken stock or other liquid. Mix together. Knead for about 3
minutes into a stiff dough. Roll the dough into 1/2 inch sheets.
Cut with cookie cutters into stars, circles, trees, bears, cats,
and rabbits, any one of which should pleasure your discriminating
dog. Place on a baking sheet. Since there is no need to let them
rise beforehand, I put the biscuits directly into a 300 degree oven
for 45 minutes, turn off the heat, and leave them overnight. In the
morning they are bone-hard and guaranteed to clean a dog's
teeth.
